Inko and Hisashi Midoriya are on a camping trip by Lake Kawaguchi, one of the Five Lakes of Mt. Fuji, to get away from the world after learning that they are unable to produce the child they always wanted. That evening, the couple see a fireball streak through the sky, following it to find a crashed spaceship with a crying baby inside. Believing it to be more than just mere coincidence, Inko insists that they take this child as their own regardless of the risks, overruling her husband's protests. And so, the baby alien became one Izuku Midoriya, destined to become the world's greatest hero.

Neither a Bird nor a Plane, it's Deku! is a My Hero AcademiaFusion Fic written by FoxOnPie. In an Alternate Universe where both DC Comics characters and concepts collide with the world of My Hero Academia, it follows the road Izuku Midoriya takes to become a Hero as an adopted Kryptonian child rather than a simple Quirkless boy, having a serious impact on his development and outlook on the world as a budding Superman in the making.

Neither a Bird nor a Plane, it's Deku! provides examples of:

Academy of Adventure: U.A. High School is All Might's alma mater and the most prestigious Hero School in all of Japan. Others include Ketsubutsu Academy High School, Shiketsu High School, and Seijin High School, but all of them exist in U.A.'s shadow. There also other other Hero Schools on par with U.A. in other countries, like Gotham Academy and the Lex Luthor Institution of Accelerated Humanity in the United States.

Tokoyami has a Reality Warping fifth-dimensional genie bound to him instead of a Quirk, giving him the single most powerful ability in 1-A.

The Ultra-Humanite is mainly known for his enormous intellect in the comics, but here he has a powerful Quirk called "Over Man" that limits the physical capabilities of all humans within 100 m of him by up to 75%. This is powerful enough to let him take on Izuku and All Might at the same time.

Hisashi Midoriya is nothing more than a pencil-pushing salaryman in the original My Hero Academia. Here he's one half of Firestorm.

Izuku meets Momo Yaoyorozu while looking for a place to eat in downtown Nagoya. After helping her retrieve her phone from a storm drain, the two bond over a shared appreciation for Princess Shazam and end up exchanging contact information over lunch to study together in hopes of getting into U.A.

While trying to come up with an excuse for his attempts to find other Kryptonians in old news articles and talking to K.E.L.E.X., Izuku ends up playing a YouTube video featuring Gentle Criminal and La Brava, who don't appear until Izuku's first fall semester at U.A. in the main story.

Kendo Rappa attends the U.A. Cultural Festival and gets into conflict with Izuku. Thankfully, it was just over a Beebo plush, and he actually walks away with a great deal of respect for Izuku's Super Strength.

According to the author, Dick Grayson went by the name of Renegade when he was a Hero. In the comics, Renegade was the name he used while working undercover as a villain under Deathstroke. In this story, though, it appears to have just been the name he used after he stopped being Robin.

In Batman: The Brave and the Bold, the Music Meister is a surprisingly dangerous supervillain who nearly managed to take over the world by singing. Here, he really isNeil Patrick Harris rather than simply being voiced by him, a Hero, and even worked at U.A. in prior years.

Giganta, traditionally a villain, is depicted as a heroine who interns with the Flashes, and the Love Interest of the younger Wally West.

Despite winning the Superpower Lottery, it's made clear that Izuku's Kryptonian strength is currently no match for a user of One For All, compared to his canon counterpart's ability to hit as hard as All Might at the cost of breaking a limb.

While Aizawa's Quirk isn't exactly weaker, it's far more of a Situational Sword because it's useless against Metahumans, magic users, and aliens compared to his home series, where he only had to worry about mutation Quirks.

Izuku is the same age as he is in canon, but as the story's equivalent to Superman he's much younger than many of the DC heroes he helped inspire in the comics, with Starfire, Renegade, and other heroes traditionally depicted as looking up to Superman being older than Izuku. For reference, the Golden Age of Heroics began decades ago with heroes like Batman and Wonder Woman and much of the Justice Society of America is long dead due to old age.

Similarly, Barry Allen, better known as The Flash, is usually depicted as a contemporary of Batman. Here he's only been active within the past decade or so, as are the Rogues. By this point, the original Batman has retired and has been replaced by the current Batman (and there were two other Batmans prior to this), Lex Luthor has succumbed to old age, while Wonder Woman has been active for decades.

According to the author, John Constantine was active at the same time as the Justice Society, making him decades older than his modern love interest, Zatanna.

Alien Invasion: Happened during the Lantern War, when the Red Lantern Corp descended upon Earth and attempted to wipe out everyone on it, which eventually turned the public's opinion against aliens in general, forcing alien superheroes to retire and go underground if they weren't killed.

Presumably, Starfire and the Martian Manhunter were able to converse with Earthlings during their time as superheroes (though it's justified in both cases by their powers). There's also Izuku, but he was raised as a Japanese human in the first place.

Izuku runs into the spawn of a Kaiju from another dimension while visiting Korusan Island to train himself. While he initially runs in terror from them, he manages to speak and reason with them while promising to go away. They only snarl back at him, but seem to understand him well enough to slink away without fighting.

All Genes Are Co-Dominant: Subverted. According to the author, it's impossible to have both the Metagene and the Quirk Factor because the Quirk Factor is dominant. The Metagene is recessive because it requires a trigger to activate. It is possible to have the ability to use Magic on top of having a Quirk, but it's very rare. Mutations from toxic wastes or lab accidents bypass all of the above, allowing Barry Allen, who has a forensic analysis Quirk, to obtain blistering Super Speed.

All There in the Manual: Several bits of lore regarding the setting are revealed in comments on Tumblr, the Spacebattles thread and replies on AO3 before they appear in the story proper. Examples include:

It's impossible for someone to have both the Quirk Factor and the Metagene because the Quirk Factor is dominant while the Metagene is recessive. Someone with a Quirk can use magic, but it's very rare. Mutations resulting from toxic waste or lab accidents, however, can give someone powers even if they have a Quirk, as seen with Barry Allen.

Those who become Heroes later in life like The Flash and Firestorm have to take night classes in order to earn their Hero Licenses.

There have been no major superhero teams since the dissolution of the Justice Society of America and the fallout of the Lantern War, but some other known teams were the Teen Titans and the Doom Patrol.

Lex Luthor had a legitimate HeelFace Turn, going from supervillain to superhero, even opening up his own Hero academy in America.

Alternate Self: Harrison Wells, Harry Wells, and H.R. Wells exist in the same world, all working at S.T.A.R. Labs to promote the greater good. They're also drinking buddies and play Secret Hitler with each other. Izuku himself is the Earth-2014.00 counterpart to Clark Kent.

And Now for Someone Completely Different: After spending the first part of Chapter 7 discussing how Izuku is going to prepare for the U.A. Entrance Exam, the story shifts to the first-person perspective of a wealthy socialite in Gotham who happens to be the granddaughter of a famous supervillain who supposedly reformed years ago. The chapter switches perspectives between Izuku and the socialite for Spring, Summer, and Autumn before they both meet in the Winter section. Said granddaughter is Alexis Lois Luthor, grandchild of Lex Luthor.

Animal Mecha: Izuku gets literally stomped on by a robot T. rex while investigating a Villain's lair in Chapter 4.

Anti-Hero: The current Batman operates outside of the law as a Vigilante. Given that this is Damian Wayne, he's undoubtedly brutal towards neer-do-wells.

Izuku: Monstars? Momo: Monstars? Izuku: Th-That just kind of slipped out! You can all ignore that, it really is kind of- Itsuka: I like it! Its a deal! [gives him a giant thumbs up with one hand]Ochaco: Really? Thats the winner? I know that its referencing an Academy Award-winning movie franchise, but- Itsuka: Nope, its the Monstars. I already changed the name of our group chat to that, and that makes it official; so let it be written, so let it be done, and all that. [all of them start laughing]

Arc Words: In Chapter 7, "For The Seasons", each change in perspective between Izuku and the socialite starts with them mentioning what season it is and "the time of year when X happens", illustrating the differences in their priorities and personalities. For instance, Izuku is driven in his reclaimed dream to become a Hero, while the socialite is too disinterested to even complete the Rule of Three in her narration.

Armor-Piercing Response: After trying his best to ignore the strange, wealthy socialite who's following him in her limo, Izuku is forced to stop when she asks if his "special" biology keeps him comfortable in the winter before outright admitting that she knows he's an alien.

Hisashi Midoriya is The Ghost in the original My Hero Academia, only being mentioned once in almost 200 chapters and not even by name. Here he's a fully-fleshed out character, a clearly doting father to Izuku and a nuclear physicist working to change the world. He's also the superhero Firestorm.

Itsuka Kendou is a side character in the original series due to being relegated to 1-B. She's in 1-A in this story and becomes one of Izuku's closest friends at U.A.

Back to Front: "The Times They Are A-Changin'" begins with Peacemaker assassinating All Might to install Melissa as the Symbol of Peace and ends with Melissa being caught in the accident that turned her into Atom Shield.

All Might mentions the magically-empowered Shazam Family in Chapter 3. Princess Shazam is also brought up in Chapter 7.

The first sidestory "S.T.A.R. Labs Interlude - And We Just Fixed the Security", reveals that the Flash Family, including both Wally Wests, is alive and active in the story as well-respected and well-known heroes in the United States. They get some action in the sidestory "Heroes Out of Crisis".

Ma Hunkel, an honorary member of the Justice Society of America, fought T.O. Morrow along with her granddaughter to save the the American midsouth from an earthquake.

The story in the present day opens much like the beginning of the manga, complete with narration about how he was going to become the world's greatest Hero, only for Izuku to throw the reader a curveball by dropping a line that his canon counterpart would never say.

The first sidestory chapter foreshadows the arrival of a Villain who is bald, light-skinned, with a probable super-genius intellect, which instantly brings Superman's Arch-Enemy, Lex Luthor to mind. It turns out that it also matches the description of the Ultra-Humanite, Superman's first supervillain in the comics.

The chapters titled "The Übermenschen" refer to the ideology of Friedrich Nietzsche, who believed that an Übermensch will transcend Above Good and Evil. The chapter's title can be translated as "The Supermen", referring to Izuku and the Ultra-Humanite, who both possess powerful abilities that can potentially change the world.

While neither Izuku nor All Might are inherently stupid, they both have Super Strength and are inherently heroic when compared to the super-genius Ultra-Humanite. But this gets zig-zagged when the Ultra-Humanite reveals his Quirk, Over Man, which lowers the physical abilities of any human within a 100 meters of him by up to 75%. This allows him to manhandle both Izuku and All Might at the same time, forcing them to use their wits to gain any sort of advantage. The Villain is only defeated after Izuku discovers his ability to fly and takes him by surprise, deactivating the Ultra-Humanite's Quirk and playing this trope straight again.

Similarly, Izuku is by no means dumb, but he's not quite as intelligent as Alexis Luthor, who graduated from college at five and earned a doctorate in nanoengineering at seven. She uses her vast connections to dig up Izuku's backstory and declares that she wants to go to U.A. to study him while hanging this knowledge over his head. Unlike the Ultra-Humanite, Izuku can't punch his way out of this situation.

Boulder Bludgeon: Izuku digs his fingers into the ground and chucks a hunk of asphalt large enough to rip off the giant zero-point robot's arm with a glancing hit during the U.A. Entrance Exam.

Even though he's fully aware of Izuku's incredible strength and was hospitalized by him as a kid, Bakugou still goes out of his way to deride Izuku and calls him "Deku" regardless since he thinks that Izuku is looking down on him by not becoming a Hero. Everyone in class lampshades the stupidity of this.

After being blasted apart by Izuku's Heat Vision and Super Breath and captured by All Might, the first thing the Sludge Villain does after escaping is attack Bakugou, inadvertently catching Izuku's attention again which in turn inspired All Might to leap back into the fray.

Bunny-Ears Lawyer: Numerous Pro Heroes and other officials are very good at their jobs, but are just as quirky as they are effective. Most notably, H.R. Wells, a co-founder of S.T.A.R. Labs alongside his Alternate Selves, mistakes an "urgent alert" as in "Danger to Central City" as an urgent alert to party.

Izuku has the standard Kryptonian powerset. Aside from him, other characters can have multiple power types at once. For instance, Barry Allen, The Flash, has a Forensic Analysis Quirk, but also has his trademark Super Speed, which came from a Freak Lab Accident. According to the author, it's impossible to have both the Quirk Factor and the Metagene and very rare to have a Quirk and the ability to use magic. It's also possible to have both a Quirk and a Mutation completely different from one's Quirk (like the aforementioned Flash). Certain Quirks can also grant multiple abilities, as All Might mentions that his hearing is enhanced while he's powered up.

Firestorm is also one of these, as his fire and EMP abilities are the individual Quirks of the scientists that compose him while his transmutation and nuclear abilities come from the Firestorm Matrix. He keeps these details under wraps out of fear that someone might try to replicate the experiment that led to the discovery of the Firestorm Matrix in hopes of obtaining two Quirks.

The Izuku of this story is a combination of the canon Izuku's personality and desires with the alien status and powerset of Kal-El/Superman.

Firestorm is mentioned by the author to be written more like his Arrowverse counterpart. As such, he's considerably more mature than many of the more recent and excitable takes on the character, but has the overall power levels of his comic book counterpart. Izuku mentions that Firestorm has won virtually every battle he's ever had due to his Superpower Lottery winning mix of Playing with Fire and I Love Nuclear Power. He displays much more of the excitable portion of his more recent incarnations after finding out that Mr. Yagi is All Might.

The Ultra-Humanite is also one of these, combining the motivations and history of his comics interpretation with the overall personality and speech patterns of his DC Animated Universe counterpart.

Dare to Be Badass: Having powers good enough to become a Hero is not Izuku's issue here, but whether or not he's willing to learn to use them to help others with full knowledge of the harm he can do if he doesn't. Hence, All Might's "You can be a Hero." moment becomes a "Do youwantto be a Hero?" moment.

Izuku falls into this while apologizing to All Might for turning down his offer to become the inheritor of One For All. Coincidentally, the conversation happened to be talking about the redundancy of getting a Super Strength Quirk when he already has Super Strength.

Izuku: Well, as great an offer it was, and it really was a great offer, I'm still really, really, really, really, really thankful for it, receiving a Quirk like that would be kind of redundant when I'm already really strong, right?

"After what seemed like hours of walking, most likely because it was hours of walking, there was no one around them. Nothing but trees and the wind."

"Any second turned out to be five seconds. Five seconds later, the new person dropped out of the air right in front of the two of them."

The creatures on Korusan Island are said to make a cackling sound that's somewhere in between "a hyena, a humpback whale, and a smaller hyena". In the same scene, the narration comments that for the head of a rotting Kaiju corpse filled with noxious, poisonous gas, Korusan Island isn't all that bad. Izuku quickly repeats the sentiment out loud.

Narration: For a decaying Kaiju head, it wasnt all that bad. Izuku: Wow! For a decaying Kaiju head, this isnt all that bad.

Disproportionate Retribution: As a child, Bakugou thought that using his Quirk to beat the crap out of a boy who took Bakugou's cupcake was perfectly reasonable. Izuku unintentionally inflicted this on Bakugou in turn, nearly killing him and leaving him heavily scarred after Bakugou left the aforementioned cupcake thief in tears.

Enfant Terrible: Brought up and played for laughs as part of Hisashi's attempts to dissuade his wife from adopting the alien child.

Inko: So what if he's an alien? It's not like all aliens are evil. The Martian Manhunter certainly wasn't evil. Besides, he's just a baby, and babies can't hurt people. Hisashi: Yeah, but the people they grow up to be can! Besides, how do we even know he's even actually a baby? [steps over to Inko and peers at the baby] For all we know, he comes from a planet of beings that just look like babies, and they all try to use their overwhelming cuteness to infiltrate societies and destroy them from the inside! [baby giggles and squeezes Hisashi's nose] That doesn't disprove the theory. [removes baby's hand from his nose]

The story "Be Humble" (Which can be read here, here, and here) is an Elseworlds story that focuses on Eri Hasigawa, who was granted the power of Shazam on Earth 2014.05/Earth 2015-E, an Earth parallel to the one the main story takes place in.

"The Times They Are A-Changin'" (Which can be read here and here) by TheInfamousMan occurs on Earth 2014.18, a world populated by the characters of Charlton Comics, where Melissa Shield gains godly abilities akin to Dr. Manhattan and tries to save an increasingly cynical and bitter world while clutching what's left of her humanity.

Everyone is a Super: The elements brought over from DC Comics, like the advent of metahumans and magic, means that an even smaller amount of the population is totally powerless. 90 percent of the population has some kind of superpower. This of course, means more Heroes and Villains, including well-known DC Heroes like Martian Manhunter and Green Lantern.

Due to the effects of the Lantern War, most people are distrustful of aliens, making it even harder for Izuku to come to terms with himself. Worse still, Martian Manhunter, Starfire, and Renegade are name dropped as Heroes who were implied to have either been killed or forced to go underground for being aliens. This has seeped into the culture at the fundamental level. Anti-alien merchandise, movies, and even textbooks are mentioned frequently in the story as part of the continual effort to make this behavior socially acceptable, which has worked, as Izuku's Super-Hearing picks up on a report that a man was arrested solely on suspicions that he was an alien. After hurting Bakugou, this is one of the primary reasons why Izuku has been laying low for so long, since Alan Scott's xenophobic tendencies would almost certainly make him hunt Izuku down if the boy's alien nature were ever revealed to the world at large.

Izuku: I don't have a Quirk, I don't have the Metagene, I can't use magic, I didn't fall in a vat of toxic waste. My powers aren't anything that belong on Earth. I'm not anything that belongs on Earth. All Might: A lot of people would agree with that. Ever since the Lantern War, people haven't been very kind to aliens. Renegade, Starfire, Martian Manhunter, we lost a lot of great Heroes at the height of the paranoia. Izuku: It's not like that's even over. Look! Up in the sky! The sun's setting, so if you look closely, you can see the light of Alan Scott's Green Palace! The space station he's been living in for almost a century to shoot down anyone like me who comes anywhere near here! And everyone's okay with that!

In Chapter 4, Izuku and All Might discover that Mt. Fuji has been turned into a massive anti-alien tourist trap. Izuku can only listen in horror as people casually talk about luring out and beating the alien into submission, with young children fully expecting All Might to come and pummel the alien if it shows. All Might is naturally disgusted with all of this, especially since he knows the alien they're referring to personally.

In an officially recognized sidestory, the Legion of Super-Heroes are all repulsed by the anti-alien sentiment of the 21st century, as many members of the Legion are aliens themselves. Brainiac 5 reluctantly refers to the period as a "fairly ugly time", when it's clear that he probably had more choice words for situation Izuku is facing.

At the same time, there are still open-minded individuals who don't think badly of aliens. All Might is one of them, as are Izuku's parents. Mina Ashido also declares Starfire to be her favorite Hero.

All Might is unable to find any evidence that shows where Izuku's spaceship was taken, but instead found a video of the spaceship fighting back against what appears to be government agents as it climbs out of the crash site while yelling in what appears to be gibberish until it says its last word for the video dies out, "KAL-ELOSH". That robot is K.E.L.E.X., Jor-El's former aide and he happens to be yelling in Kryptonese.

At the U.A. Cultural Festival, the big guy Izuku was competing against for the Beebo doll said he wanted to win the thing as present for his boss's daughter. The man is Kendo Rappa, one of the Eight Expendables of the Eight Precepts of Death.

Because this fic crosses over with the DC Comics with their metahumans and magical abilities, 90% of people have superhuman abilities rather than the 80% worldwide percentage the My Hero Academia canon has.

The moment when Izuku defended another boy from Bakugou was a defining moment for both boys in canon, cementing each others' ideologies. This time, Izuku has Kryptonian powers making it so he can fight back, and the encounter doesn't end well for either of them.

Due to the highly public nature of Mt. Fuji and leaving their car at their camp site, the Midoriyas were only able to take the baby Izuku and the lid of the spaceship rather than the whole thing as the Kents did. Hence Izuku has no way to learn about his home planet's culture, only knowing that he's an alien. After meeting All Might, he spends the next part of the series hunting this ship down in order to gain some closure.

Subverted with the Sludge Villain incident. Izuku's powers would have let him easily defeat the Sludge Villain, but he refuses to use them out of fear of being labeled a Vigilante, requiring All Might to save him again. He also runs to save Bakugou from just like in canon, but this time he successfully tears Bakugou free and tosses him to safety. He still gets chewed out by the Pro Heroes for intervening even though the crowd of onlookers cheered while seeing him in action.

Due to his already incredible abilities, Izuku refuses One For All because he feels that it would be wasted on him. According to the author, this means that Mirio Togata, the one originally scouted to be All Might's successor, will be getting it instead of Izuku. When and how is still up in the air. This also means that Izuku isn't going to go through the same Training Montage as his canon counterpart, instead spending the time before the U.A. Entrance Exam trying to hunt down his spaceship so he can learn about where he came from.

Numerous readers have pointed out that many of the battles that Izuku struggled with in canon, such as his fight against Hero Killer Stain, would be trivialized by his Kryptonian powerset. The author responds that this is assuming that Izuku fights all of the same Villains that he does in canon.

Because Izuku helped several applicants during the entrance exam, while also unwittingly stealing some points (eliminating robots that would have granted points to other examines) and inspiring a number of applicants into helping each other (which earned them many Rescue Points), he changes the canon scores. He ends up with the highest score in the exam's history while Bakugou ends at the bottom of the top ten instead of the canonical first place. Also, Itsuka Kendou joins Class 1-A instead of Rikido Sato.

Free-Range Children: Izuku and Bakugou used to hang out together without any adult supervision as per canon. Unfortunately, this means that no one was able to stop them from brawling after Bakugou starts bullying another kid, ending with the former nearly dying after being thrown through a wall by accident.

Izuku has the muscle of a Kryptonian but also the smarts to use it. When speaking with Firestorm, Izuku manages to flip the conversation around to manipulate the Pro Hero into allowing him to help find the alien spaceship with his natural modesty, shocking All Might. Aside from this, he's also able to pick up on obscure clips of music like Czech composer Leo Janáček's "The Cunning Little Vixen" and knows slang words from other countries like "schway". Then there's his canonical encyclopedic knowledge of virtually every major Hero in the world.

The Ultra-Humanite proves to be one as well, being strong and skilled enough to take on Izuku and All Might at the same time while the latter was under the effects of his Quirk.

All Might is an extremely competent hero and is said to have a 6/5 in Intelligence according to his official power ratings.

Gratuitous German: The fifth and sixth chapters of the story is titled "The Übermenschen", literally "The Supermen". More literally, this can also be read as "Over Men", referring to the name of the Ultra-Humanite's Quirk, granting him a nearly absolute physical strength advantage over humans or in other words, putting him over men.

Great Offscreen War: The Lantern War happened long enough ago that Hisashi's father took part in defending Earth from alien attack, which contributes to Hisashi's own hesitation in adopting Izuku.

The Greatest Story Never Told: Izuku's involvement in the Mt. Fuji incident gets covered up by All Might and Firestorm to keep the boy out of trouble.

The Heavy: Atrocitus and the Red Lantern Corps. Decades prior to the story, they invaded Earth and fought against the Green Lanterns in the Lantern War. This led to the public growing to hate aliens and see them as monsters, which is part of the reason why Izuku hated himself so much for what happened to Bakugou.

Heroes "R" US: Heroes are registered with the government and are given licenses to operate out of Hero Offices. They get paid for their work and can even merchandise their image. Izuku's "Beats by Canary" headphones are marketed by Black Canary and he owns entire collections of All Might merchandise. He also has plenty of merchandise from other Heroes as well, bringing Justice Society figurines to entertain the Mi-Gos.

Hero-Worshipper: Virtually everyone in 1-A and some Pro Heroes have a Hero they Squee! over, but no one is as much of a hero nerd as Izuku.

Homosexual Reproduction: The questions on the written portion of the U.A. Entrance Exam reveal that Casey Brinke and Terry None were able to use their abilities to create a drug that allows women to impregnate other women, making this a possibility. Momo is one of the products of such a relationship.

Hisashi initially refers to the alien baby as "it" until Inko corrected him by saying that the baby is a "he" after looking in the baby's diaper.

At Mt. Fuji, the visiting children refer to the alien as "it" while Izuku is in earshot.

The Knights Who Say "Squee!": Izuku's enthusiasm for all things Hero-related is undiluted. He fills out his Hero Analysis journals, squees so hard when meeting All Might that his bows are scraping away at the pavement, and rambles on and on when asked about the details of any particular Hero. Firestorm's professionalism collapses when "Mr. Yagi" reveals himself to be All Might, squealing like a rabid fangirl even as Professor Stein is implied to be telling him to calm down.

Landmarking the Hidden Base: Firestorm comes to Japan in Chapter 4 to hunt down a Villain who was believed to have set up shop in the area. He and Izuku find out that said Villain has built a base inside Mt. Fuji, arguably Japan's most recognizable landmark, even before Izuku's spaceship had crashed at the base of the mountain. The Villain also mentions that he didn't actually construct the base himself, rather it was hollowed out long before he had arrived.

Last-Name Basis: All of the Japanese characters in the story are referred to by their surnames with the exception of Heroes and Inko and Hisashi Midoriya. By contrast, the American characters introduced in the story are all referred to by their first names if they don't have a Hero Name.

All Might is the eighth wielder of One For All, having inherited it from Nana Shimura, who in turn inherited it from the six wielders before her. He wanted Izuku to be the ninth, but Izuku refused on account of having a ton of other Combo Platter Powers to master and the redundancy of giving a Super Strength Quirk to him.

In Chapter 5, Izuku mentions that there has been more than one Batman, comparing his role as the "Dark Hero" to Endeavor's in the present.

In the same chapter, Izuku also mentions that Jay Garrick, the first Flash, was part of the original "Trinity" of superheroes, the others being Wonder Woman and Batman. His title as the Flash was later succeeded by Barry Allen and his nephews, both named Wally West.

Mad Scientist: Izuku's second real Villain encounter is the Ultra-Humanite, Superman's first supervillain.

The Magnificent Seven Samurai: Discussed. Momo laments the fact that her new group of friends with Izuku, Ochaco, Tenya, and Itsuka only has five people in total. If they had two more they could have been the Seven Samurai.

In "Hope Carried 1,000 Years", an assassin from the 31st century traveled back in time with a Kryptonite bullet, intent on assassinating Izuku before he becomes Superman. Luckily, the would-be assassin is foiled by the Legion of Super-Heroes.

"Time and Chance (1): How the old Ice-Cream Parlor will Change" shows that this wasn't even the first attempt on Izuku's life. Brainiac assimilated a two-bit Villain named Koujou Joubu as a proxy to deal with Izuku when he was five years old and vulnerable.

Mecha-Mooks: The Villain lair Izuku finds in Mt. Fuji is filled with them, ranging from humanoid robots to half-spider things to robot T. rexes. It also gives him a good excuse to burn one's arm off with his Heat Vision.

The Men in Black: Mentioned by Hisashi as part of his hesitation in adopting Izuku. Later, a group of mysterious unnamed individuals intervene while Shitsugen is interrogating the Midoriyas and Bakugous, taking over the investigation as Izuku blacks out from the stress of his Super-Hearing.

Hisashi: If anyone finds out that we were the ones who took him, our lives are over, Inko. I work in government, I hear whispers about this all the time. Guys in black suits will be at our doorstep in the dead of night to cart us off for interrogation and torture. After that, all of our neighbors and family will think we just disappeared, when really we "disappeared". Do you want that to happen?

Nervous Wreck: Izuku is even more of a nervous mess than his canon counterpart due to his fear of hurting others if he's not careful. That said, he lets Bakugou know when he's upset by throwing him against the wall hard enough to unbutton his shirt when Bakugou blows up Izuku's Hero Analysis notebook like he does in canon, though he's quick to put his bully back on his feet soon afterward.

His father Hisashi isn't much better at the start of the story, descending into hysterics and conspiracy theories after he and Inko took Izuku from his spaceship and ran away with it. He seems to have mellowed out for the most part after years of raising Izuku with Inko, who has taken up the role of being the family worrywart.

Never Trust a Title: Although the title would imply that Izuku would take up Deku as his Hero Name, the author states that Izuku will end up being Superman instead.

No Ontological Inertia: The primary weakness of fifth-dimensional beings is that all of the direct effects of their Reality Warping vanishes the moment they're banished back to the Fifth Dimension.

Oh, Crap!: Many characters have this reaction over the course of this story.

Izuku is on the verge of having a Freak Out when All Might deduces Izuku's identity as the alien humanoid who injured Bakugou ten years prior the main story. He starts panicking again in Chapter 6 when he realizes he's being held hostage by one of the most venerated Villains in the world, the Ultra-Humanite.

All Might has this reaction when he realizes that he's run out of hero time, forcing him to revert to his withered state in front of Izuku.

The Ultra-Humanite has this reaction when he realizes that his Quirk has been deactivated, leading to his Precision F-Strike. He has it again when All Might and Firestorm to rush in to kick his ass after Izuku exposes this fact.

Old Superhero: Ma Hunkel, the original Red Tornado, is well into her golden years when she battles T.O. Morrow along with her granddaughter and All Might.

"Izuku Midoriya: Birthright" serves as the typical "Kal-El arrives on Earth" story followed by "Izuku decides to become a Hero". Meanwhile, The Übermenschen Part 3 reveals the story's version of the events leading up to Krypton's destruction.

The sidestory "The Boogie Woogie Bugle Boys and Girls" reveals how the Justice Society of America got together.

Papa Wolf: All Might becomes extremely protective of Izuku and vows to defeat the Ultra-Humanite after the latter seemingly kills Izuku. Firestorm is even more so, threatening to turn Mt. Fuji into a pillar of salt for the same reason. Of course, his rage is understandable when it's revealed that he's Izuku adoptive father.

Person of Mass Destruction: All Might can generate massive windstorms with his movements and veritable twisters with his punches. Firestorm also threatens to turn all of Mt. Fuji into a pillar of salt in anger after Izuku seemingly dies.

On the superhero level, you have heavy-hitters like All Might and Wonder Woman, who are universally considered Earth's strongest Heroes at the story's outset. They're strong enough to level skyscrapers and change the weather with their punches, regularly stop villains trying to cause national disasters, and are generally head and shoulders above their peers in power. Izuku's growing Kryptonian powers give him the potential to become this with time and training, but he's admittedly far inferior to All Might and Wonder Woman in the present.

At the top are the truly primordial and abstract beings like the Endless, anthropomorphic personifications of the facets of the universe like dreams, death, and destruction.

Poor Communication Kills: Just like in canon, the defining trait of Izuku's and Bakugou's relationship. There are too many misconceptions between them to count, but the greatest one is, perhaps, Bakugou's belief that Izuku is looking down on him and doesn't believe he can be a hero. In reality, Izuku looks up to him, and probably has the most faith in Bakugou next to the boy himself.

Punny Name: In the Elseworlds story, "Be Humble", Eri (who is Shazam on Earth 2014.05) attends Jaguchi City Elementary School under the pseudonym "Ringo Raiku". Jaguchi can be translated to "Faucet", a homonym for Fawcett City, the hometown of Billy Batson.

Pro-Human Transhuman: Numerous alien Heroes were this in the past, but are implied to have either been killed or forced underground due to Fantastic Racism. Izuku himself is one, thinking himself no better than anyone else on Earth even though his incredible abilities outclass most other Quirks on the planet in terms of raw power and usefulness.

Race Lift: The person controlling Firestorm's body is Japanese, as opposed to the Caucasian Ronnie Raymond or the African-American Jason Rusch.

Reformed Criminal: Victor Fries, better known as Mister Freeze, quietly surrendered after a fight between him, the first Batman, and the fourth Robin accidentally ruptured the cryostasis tank holding Fries' wife, Nora, who had been miraculously cured of her debilitating illness by the Quirk she manifested while she was on ice. He then spent fifteen years as a model inmate in Arkham Asylum and even helped foil numerous breakout attempts by the other supervillains before leaving a free man and starting Fries Financial, an incredibly successful conglomerate on par with Wayne-Powers, Queen Consolidated, and Lexcorp.

Retired Badass: Although she's officially retired and likely well into her golden years, All Might mentions that Ma Hunkel, the original Red Tornado and an honorary member of the Justice Society of America, helped him battle T.O. Morrow along with her granddaughter a week before the U.A. Entrance Exam.

Scene Of Wonder: Izuku is awestruck when he gets to see Krypton (as a hologram) for the first time, marveling at its architecture, locales, and technology as he comes to grips with the fact that this is where he came from.

For the most part, subverted due to the public and regulated nature of Heroes in the My Hero Academia universe. All Might is one of the only Heroes playing this trope straight due to his need to keep up his image as the Symbol of Peace, letting only a select few people see his True Form. Izuku also does this to a more limited extent, being careful not to let anyone know the true nature behind his powers or to keep himself and his parents out of trouble, though it's somewhat subverted since the police, government, and top ten Heroes are already aware of his existence due to that fateful day when he was four years old. The government is also keeping tabs on him, allowing Alexis Luthor to get a general idea of his life story.

Chapter 4 reveals that All Might does this two-fold. In public, he uses the pseudonym Hikaru Hinata. Meanwhile, he works as his own secretary under his actual name, Toshinori Yagi. That way, the people working at his Hero office won't be able to make a connection between the two. Lampshaded by Izuku.

Izuku: That's so cool! It's like how Heroes disguised themselves as normal people before the Golden Age Act was passed! All Might: I know, right?! That was the only thing on my mind when I came up with it! Who doesn't love a bit of nostalgia, right?

The test questions on the U.A. Entrance Exam reveal that all of the Robins except for the fourth one (Damian Wayne) revealed their identities to the public to take a more active political role in addition to their heroic activities. The Golden Age Act also allowed Heroes who were active before the establishment of the Hero system to keep their identities a secret, but all subsequent Heroes are required to make their names known to the government (but not necessarily the public).

Like in canon, Izuku is keeping All Might's true form a secret from the public after accidentally seeing it. All Might in turn is keeping Izuku's identity as an alien secret, since he believes in the good Izuku is capable of.

Firestorm and the Ultra-Humanite agree to keep their knowledge of Izuku's identity as an alien and All Might's true form a secret in Chapter 5.

In Chapter 7, Lexi Luthor reveals that she knows Izuku is an alien, but seems to have no intention of revealing this to the public for the moment.

Chapter 8 reveals that U.A. knows that Izuku is an alien. They grumble about it while watching Izuku's performance at the entrance exam. As much as All Might would like to support him, he can't blame them for their discomfort. The following chapter reveals that the government informed them.

In Chapter 10, Dark Shadow reveals that he figured out Izuku's identity while feeling him up in the previous chapter. He promises to keep it a secret from Izuku's classmates, but he already blabbed about it to the other fifth-dimensional beings, which draws Mister Mxyzptlk to Earth and throws Izuku's morning routine into chaos.

Suicide Attack: A four-year old Izuku remembers a fight between All Might and Lord Death Man, where the latter attempted to blow them both up with a powerful bomb strapped to his chest. Due to Lord Death Man's regeneration Quirk, he would survive while All Might would not. Luckily for the Hero, he managed to throw Death Man off of him with his Oklahoma Smash. resulting in Lord Death Man's defeat. This is what inspires Izuku to emulate All Might while fighting Bakugou, which ends disastrously.

Due to differing jurisdictions and having his own hands full with the Rogues and Black Hole, Barry Allen, better known as The Flash, decides not to intervene after S.T.A.R. Lab tech is stolen and is en route to Japan, simply alerting the Japanese Hero community to let them handle it.

Subverted with Firestorm, who is Japanese in this story. While he does most of his work in America, he comes to Japan in search of stolen S.T.A.R. Labs tech in place of the Flash.

Firestorm is also mentioned to be a super powerful Hero, winning practically all of his battles over the course of his seven year career thanks to his potent mix of Playing with Fire and I Love Nuclear Power which also grants him Flight.

All Might's Quirk, One For All, is one of the most powerful in the world. He can easily overwhelm Izuku's teenage Kryptonian strength and speed even after losing much of his power to an injury he received five years before the events of the story.

Tokoyami puts them all to shame with his possession of a fifth-dimensional genie, potentially making him a Reality Warper on par with Mister Mxyzptlk if he can formulate the right wishes.

While the Japanese government doesn't have Izuku under constant watch, it generally keeps tabs on him after he nearly killed Bakugou when they were children. This lets Alexis Luthor obtain Izuku's life story with her connections, thoroughly unnerving Izuku when they finally meet.

As per canon, the testing sites for the U.A. Entrance Exam are littered with cameras for the proctors to observe the students with.

"Test Your Strength" Game: The punch strength variation is set up at the U.A. Culture Festival. Izuku immediately runs up to win it with his Kryptonian Super Strength after spotting a rare Beebo doll among the prizes. His plans are cut short when it turns out that Kendo Rappa is after the same doll. While Izuku initially tries to back out, the two end up getting egged on into a strength contest that ends with Izuku destroying the machine while actively trying to lose. The strength levels range from city-destroying, to country-destroying to planet-destroying, to wrecking the space-time continuum itself. The student manning the stall admits that she didn't know it went that high.

There Are No Coincidences: Inko considers it fate to have found Izuku after discovering that she is infertile, using this trope to justify adopting him over her husband's protests.

Inko: Hisashi, don't you think that we need to be doing this? The whole reason we were there was because we wanted to forget about the fact that we could never have a child of our own, and then a baby falls into our laps? That can't just be a coincidence. Hisashi: It is absolutely a coincidence! If you looked up coincidence in the dictionary, the definition would read "What is happening to Hisashi and Inko", right now!

There Are No Therapists: Izuku and Todoroki suffer from severe psychological issues. The former is plagued by his constant guilt over nearly killing Bakugou and his fear of being outed as an alien, while the latter has Abusive Parents who have left him an aloof, stoic Jerkass who wants nothing to do with his father or his powers. Neither of them are able to seek out therapy because of the root causes of their problems. K.E.L.E.X. even recommends Todoroki to visit a therapist, but Izuku shoots down the notion immediately.

K.E.L.E.X.: IT WOULD NOT BE UNWISE TO ASSUME THAT HIS ATTITUDE STEMS FROM SOME MANNER OF PSYCHOLOGICAL ISSUES. I SUGGEST INFORMING HIM OF THIS AND DIRECTING HIM TO THE NEAREST THERAPIST. Izuku: Yeah, thatthere's no way that could be a good idea.

Too Dumb to Live: The Kryptonian Science Council, as usual, refused to heed Jor-El's warnings of Krypton's impending destruction despite seeing photographic evidence of Krypton's destabilized core. Naturally, this doomed the entire Kryptonian race and Jor-El was only able to scrounge up just enough resources to finish Kal-El's ship before the planet's destruction.

20 Minutes into the Future: The story's technology level is somewhere in between My Hero Academia's and Batman Beyond's. There's plenty of futuristic technology that's used to support Heroes and holograms are cheap enough to be used commercially (even if they are vastly inferior to the ones on Krypton), but there aren't any commercially available flying cars or things that would radically change the quality of life in Japan. It's also implied that the story is still taking place in the 21st century, as the Justice Society of America was formed when President [Franklin Delano] Roosevelt was in office.

Unobtanium: DC's numerous supernatural metals, such as Nth Metal, are brought up as rare and valuable materials throughout the story. They're difficult to acquire due to their supernatural properties and are often hoarded by specific factions, such as feminum for the Amazons. Uraraka's costume is made of an feminum alloy hard enough to crack Iida's armored costume. Hisashi also pulled some strings to get Seventh Metal fibers to weave into Izuku's Hero costume, making it similarly durable.

What Measure Is a Non-Human?: A driving source of conflict in the story is that the majority of the public is aligned against aliens, even Human Aliens, because of the destruction wrought during the Lantern War. Amazons and Atlanteans have also been mentioned, but the word is out on the public's general opinion of them.

Womb Level: While scouring old newspapers and tabloids in hopes of finding any signs that another Kryptonian could have survived Krypton's destruction, Izuku comes up with the idea of using Korusan Island, a structure a kilometer off the coast of Japan, as a training ground for his powers. The "island" is actually the corpse of a Kaiju that was killed by Big Science Action three years prior to the main events of the story. It turns out to be a perfect stomping ground for Izuku due to its massive size and the fact that it constantly releases a corrosive, poisonous gas that can kill Earthlings and dissolve any Earth metal in seconds, minimizing any chance of him being discovered. At the same time, the interior of the island is well-lit due to the bioluminescent crystals growing inside, and the floor is soft and squishy like Tuscan grape stomping. Of course, there's still plenty of rotting brain matter, flesh, and shards of bone, but these don't bother Izuku much compared to the sharkheaded tentacle creatures he runs into soon afterward.

Unlike canon, in which the year is left deliberately vague, the author uses the year 20XX to describe the time period. This makes conversations hilariously confusing when the year is brought up.

Pathetic! You're all pathetic! It's not 20XX, anymore, it's 20XX, for crying out loud! Be better than this and don't bother me when all you have to offer is mediocrity!

All Might mentions that his car was only manufactured in 198X and the old Beebo cartoon ran in the 19XXs. Izuku also says that the Justice Society was founded by suggestion of President [Franklin Delano] Roosevelt, implying that it's still in the 21st century.

Zerg Rush: Izuku, Firestorm, and All Might are swarmed by legions of robots while investigating Mt. Fuji. Firestorm ends up taking out the majority on his own, but more appear when they confront the Villain responsible.
